CDRwin Won't write

[StingyOne]

I'm having a problem getting cdrwin to write.
It can read the disc fine. So far I've only got it to save a cue sheet.
But when I go to write the cd, all it does is spin the disc in the cd-rw on and off and just ruins the cd. The only thing I could think to be wrong is that i don't have any SCSI bus transporters installed. Would this cause the problem?
I'm not even sure what the transporter would do.
